When Madison homeowners ask about sump pump installation & replacement
- Pump cycles every few minutes, even in dry spells
- Pit with no pump, or a pump that hums but doesn't move water
- Discharge hose ends on the lawn and the water comes back
- Discharge plumbed to a floor drain
- Ice building up where the hose ends
In Madison the discharge point matters as much as the pump. City Engineering says it can't go to the sanitary sewer, and a pump that runs several times a day should go to the storm sewer if at all possible.

What Madison Engineering says
Where a Madison sump pump can discharge. City Engineering says sump discharge to the sanitary sewer, such as a basement floor drain, isn't allowed. Its listed options are discharging onto the property, directly to a storm sewer if one is available (typically within 100 feet), to the curb, or to an infiltration bed. A pump that runs often should go to the storm sewer if at all possible, which reduces algae in summer and ice in winter (City of Madison Engineering, Sump Pumps).

Sump Pump Installation & Replacement questions
What will sump pump installation & replacement cost in Madison?
There is no single price. The cause, the method and the size of the job set it. The cost guide lists published 2026 ranges, and the contractor gives you a written quote after seeing the basement.
How fast can a contractor come out?
That depends on who is available. Spring melt and storm weeks fill schedules first. Send the form and we'll see who can visit.
Where can my Madison sump pump discharge?
Not to the sanitary sewer or a floor drain. City Engineering lists the yard, a storm sewer within about 100 feet, the curb, or an infiltration bed. A storm sewer hookup needs an Excavation in the Right-of-Way Permit and a contractor qualified to work there.
Are you a waterproofing company?
No. Madison WI Basement Waterproofing is a referral service. We pass your request to an independent basement contractor who works in the Madison area, and that company does the inspection and the work.
